Image acquisition process simulator

Abstract : In order to design a new sensor, exploring acquisition mode options before manufacturing allows to measure their impact on the quality of resulting image and image processing. This exploration can even be done to optimize a sensor for a given application. Hence, from the very beginning of the design of conventional or unconventional sensors, mastering picture acquisition process is a keypoint to take into account every physical phenomenon that affects image quality. To achieve this goal, an image acquisition process simulator has been designed. In order to get accurate and reliable results, the simulator had to match physical phenomena (e.g. diffraction) and to model noises. The simulator has been designed to be as modular as possible to model pixels with various function modes-for instance a differentiated-by-zone acquisition mode-, different sizes, several spectral bands, several acquisition times, different reading orders. Our simulator can also model systems whose optical design is more complex, knowing their optical transfer function. Every step of the simulation has been evaluated and the simulator has been globally tested on point sources, simulated and real pictures and aerial high definition pictures.
